Abstract

Laminar forced convection about a rotating sphere that is subjected to a uniform stream in the direction of the axis of rotation has been numerically investigated. The boundary-layer equations governing this case have been solved by means of a finite-difference scheme for a fluid of Pr=0·7 over wide ranges of Reynolds number (Re) and Taylor number (Ta). Both the isothermal and constant-heat-flux thermal boundary conditions have been considered. A comparison with data available in the literature has been made. Results not available in the literature, at considerably large values of the spin parameter (), are presented for the local and average Nusselt numbers.
